nosn-cournm'e.

To all whom it may concern:.

Be it knownthat I,1J 01am H. V 4 zen of the.United-.States,' residing at Lam- 'bertv'ille, in the county :of .Himt erdon; and

State, of New Jersey, have invented new and which the following is aspecification; i

My present invention-relates to improve ments in hose couplings and especially to that class employed for the purpose of con necting the air and steam hose 'on-railw-ay trains, and the primary objector; the invention is to provide an improved coupling of this character wherein the cuteofi 'valve which controls the fiowf 0t. fluid .from the train pipe on each car is opened automatically when the members-of the coupling are properly joined. 7 Another object of, the invention is to pro-V vide a couplingof thisvcharacteifwherein the usual angle cock'may.- be dispensed with, an appropriate cut-off or controlling valve being inc osed within the head of the coupling member sothat it cannot become accid'en tally or; .meliciously deranged, a fault which is inherent .in' the'useoi-the angle cock. v

Further oh ects ofv the invention are to provide a novel mode of mounting the auto matie-cut-ofi valve in the headof the coup,

301 c rnember, and to. provide a device which operaterto retain the valye in open position. should the, members become accidentally nncouplei so that when thecouplings are used in -.c onnection with the train pipe'of an air-brake system, the ,brakeswill he antonn tically set should the coupling be broken byreason of-the uncoupling of the cars orl'from -other causes;

novel features being pointed out particu- I larly in the claims at the end of the specifi- V v v v To 'tlresfe ahd other ends, the inventionconsists in certain improvements, and com-.'

final act of coupling the hose insures the; proper opening of" the-controlling valves on the adjacentends of both cars-and as the valves are concealed; the possibility of ma-' licious tampering therewith is precluded. In theI'p-resent embodiment of my inven- 'tion thei coupling head'iis attached to the free endof the usual'hose connection 1, the

latterbeing connected at its upper end to the usual train pipe 2. maybe made in any-suitable manner, it

The coupling head being composed in the presentinstanceof l two component sections 3 and 4 which are securedtogether by means of bolts or suit- '-ahle"dev1ces'5.' The section 3 is provided witha longitudinal bore and a nipple 6 over which the hose 1fits,'and the section4 is pro- 1 this valve member, This cam projection vided with devices which interlock with a cooperating coupling member. The coupling shown in the present instan-.:e is of the .well known type wherein the members are coupled and uncoupled by a relative rotary movement on a transverse the section 4 of each coupling member being provided with the usual cam-shaped lugs 7 and S which interlock in the well knownimanner with a corresponding pair of lugs of another coupling member, the cams on these lugs being of segmental form and serving to draw the coupling members together transversely. That face of each coupling member which engages a cooperating coupling member is provided with a chamber 9 'Wl'llOll communi cates with the bore of the section 3 and fitted into this chamber is' a valve member 10 having a central air passage 11 and a conical valve seat 1'2 surroundingsuch passage. This valve member is provided with an annular guide 1.3 which is arranged centrally of the chamber 9 and is connected to the valve seat by means of radial ribs 14, The outer sides of these ribs serve as seats fora packing washer 15. The outer end of the chamber 9 is provided with an internal flange 16 through which a sleeve-like portion of the washer 15 extends, the washer having an inner peripheral flange 17 which rests upon the outer sides of the ribs 14 of the valve member and bears against the rear side of the internal flange 16.

A valve member 18 is mounted to reciprocate through the bore 11 of the valve seatv and the guide 13 supported thereon, this valve member having a conical head 19 which cooperates with the seat 12, the valve head and seat being normally held in co operative relation to confine air in the train pipe, by means of a helical compression spring 20 which surrounds a guiding stem 21 fixed in the coupling section 3 and serving as a guide for the valve member 18. It is generally preferable to construct the chamber 9- in the form of a cylinder which opens at the inner or lower face of the section 4, such a construction permitting the valve member 10 to be introduced into the section 4 while the latter is detached from the section 3, and by interposing a sheet of packing material 22 between these two sections and clamping the sections together, the lower side of the valve seat 10 bears upon this packing material to provide a fluid-tight joint, and the clamping together of the two sections also causes the ribs 14 to bear against'the rear side of the washer 15 and thereby hold the latter tightly against the internal flange 16 a seat.

The outer end of the valve member 18 is an incline extending diagonally of the axis of in open position,

occupies such an angular position relatively to the cooperating locking lugs of the coup.: ling members, that when the two coupling members are brought together, the cam pro- 7 jections on the respective valve members will be offset relatively toone another, as shown in Fig. 10, the twovalves, however, at this time remaining closed so as to prevent the escape of air from the train pipes. When 7 the coupling members, however, are rotated on a transverse axis in the usual manner to lock the cou iling members, the valve members 18 of the respective couplings will be caused to. rotate in reverse directions or in a 8 direction indicated bythe arrows in Fig. 10, and such movement of these valve members will cause the two cam projections to ride upon one another and thereby move the tion, displacing the valve heads 19 from the respective valve seats 12, as shown in Fig. 3, thus establishing communication between the train pipes on the respective cars.

valve members inwardly in an axial direc- In order to prevent rotation of the valve members 18 relatively to the respective coupling heads, these members are preferably providedc y ith transverse slots 24 through which a slidew25ioperates transversely, this slide being ter is operatively connected to a lunger 27 having a push button 28 whio operates through one side of the coupling member and is accessible for operation on the exterior thereof.

The slide 25 has a reduced and which is considerablmrrower than the length of the transverse slot 24 sothat while this reduced porti'onof the slide rests in such slot, the res ective valve member is 1 free to close. A s ioulderor thicker portion 29, however, is formed on this slide which,- wllile it engages in the slot 24, will prevent closing movement of the valve member, and

the normal tendency of the slide 25 is to carry this shouldered portion thereon into the slot 24 under the-action of a compression spring 30 which operates upon the plunger Ordinarily while the valve member 18 is in closed position, the shouldered end of the 11 .head from the corresponding seat by the coupling of the two members, the enlarged portion 29 of the slide will spring into the slot 24, and will thus serve to lock the valve members become accidentally discoimected, the controlling valve will remain open, per, mitting air to escape from the train pipe and thereby set the brakes on the respective car or cars. .However, the brakeman in unpivotally terse-seame its free end to a bell-cram: lever 26, and the lat- Should the coupling 5 couplingthe members maydepress the push button 28-which will cause the slide to be other and thereby permit closing of the re I 0;j -spective valves; 1 V

' -A hosecoupling constructed in .accord- ;q an'ce' with my present invention may be gilanipulated with the greatest facility, as

open the cut-oft valves on the respective car's. For this reason, the tendency toward accidents in operating trains, 'either through failure to open the usual'hand operatedangle cook, or the accidental closing thereof is eliminated. Moreover, as the valve is totally concealedafter the members of the -.coupling have been locked, it is impossible I ,to maliciously tamper therewith.

detaining device also'acts automatically to retain the valve in open position and thus the brakes, should the coupling members hecome accidentally disconnectedbecause of the uncoupling of the cars, although, by depressing the push button previous to the dis connectionofthe. coupling members, the valves will automatically close when the coupling members are separated, and thus prevent setting of the brakes.

:The invention isnotnecessarily limited 'in'its application to hose couplings of the type shown wherein the members are locked and unlocked by a relative rotation on a 1 transverse axis, although it is generally advantageous to apply the invention to couplings of such type, as thesefcouplings co,n-.
